自建集群

最后更新时间：2024-08-13 17:22:21
本文介绍接入自建集群的步骤，您可以将自建集群接入容器安全服务进行统一管理，对自建集群开展集群风险检查和管理。
说明
K8s 集群支持1.13以上版本。
限制条件
接入自建集群节点规模小于500节点。
操作步骤
1. 登录 容器安全服务控制台，在左侧导航中，单击集群安全管理 > 集群检查。
2. 在集群检查页面，单击接入集群。
﻿
3. 在集群接入页面，选择所属云为腾讯云或非腾讯云。
腾讯云：自建集群的云服务器资源来源于腾讯云，需按页面提示选择推荐安装方式和集群名称。
﻿
非腾讯云：选择非腾讯云，按页面提示配置推荐方案方式、集群名称、命令有效期。
说明：
接入集群的云服务器资源来源于其他云，包括其他云的自建集群、独立集群、托管集群等。
﻿
4. 单击生成命令，可复制并执行相关命令。可以下方下载或复制 Yaml 文件内容，并通过以下两种方式安装。
说明：
建议您针对单个集群生成单个接入命令，以避免集群名称重复。
方式一：单击复制命令链接，拷贝到可以执行k8s命令的机器执行。您也可以先下载下方Yaml文件，拷贝到机器上并执行 kubectl apply -f tcss.yaml。
方式二：前往 容器服务控制台-集群详情页面，通过“使用 Yaml 文件创建资源”复制命令内容。

5. 安装后，检查是否安装成功。集群接入后，将会在该集群创建“tcss 命名空间”，并创建如下工作负载资源，需确保以下3个工作负载正常运行：
tcss 命名空间下安装名称为“init-tcss-agent”的 Job 类型工作负载。
tcss 命名空间下安装名称为“tcss-asset”的 Deployment 类型工作负载。
kube-system 命名空间下安装名称为“yunjing-agent” 的 DaemonSet 类型工作负载。
5.1 检测 Job 工作负载是否部署成功。
查看 Job 是否创建成功，执行命令：kubectl get jobs -n tcss。
﻿
查看 Job 是否部署成功，执行命令：kubectl get pods -n tcss | grep init-tcss-agent。
﻿
5.2 查看 DaemonSet 是否部署成功。
查看 DaemonSet 是否创建成功，执行命令：kubectl get daemonset -A -l k8s-app=yunjing-agent。
﻿
查看 DaemonSet 是否部署成功，执行命令：kubectl get pods -A -l k8s-app=yunjing-agent。
﻿
5.3 检测 Deployment 工作负载是否部署成功。
查看 Deployment 是否创建成功，执行命令：kubectl get deployment -n tcss。
﻿
查看 Deployment 是否部署成功，执行命令：kubectl get pods -n tcss | grep tcss-asset。
